The wording suggests that John McCain is bumbling and out of touch — underscoring Obama’s generational appeal and hinting obliquely at McCain’s age — 72 as of Friday.

The ad was billed as a response to McCain’s selection Friday of Alaska Gov. Sarah Palin as his running mate. But mainly, it’s another chance to show McCain with President Bush — twice in 30 seconds.

The ad is called “No Change." An Obama release says it shows “how John McCain’s choice will not change the fact that he still desires to just offer four more years of the same failed Bush policies.”

Here’s the script:

Female narrator, over dreary music: “Well, he’s made his choice. But, for the rest of us, … there’s still no change. McCain doesn’t get it, calling this broken economy ‘strong.’ Wants to keep spending $10 billion a month in Iraq.”

Then it shows McCain walking with Bush in the Rose Garden: “And votes with George [Bush] 90 percent of the time.”

And McCain presenting Palin at their Ohio rally: “So, while this may be his running mate …”

And Bush hugging McCain: “… America knows this is John McCain’s agenda.”

And a photo of the White House: “And we can’t afford four more years of the same.”

Then Obama says: “I’m Barack Obama. And I approve this message.”

Obama drew cheers and applause when he said in his acceptance speech at Invesco Field at Mile High in Denver: “It's not because John McCain doesn't care. It's because John McCain doesn't get it.”
